Last year I ran a personal values workshop for some teammates which was a fun and valuable exercise. There are lots of suggestions on how to run a workshop like this on the internet. I picked one that would work well remotely. Everyone created their own values board individually, and we had time at the beginning and end for discussion to make the sesion more interactive. The workshop fit into a one hour session but some of the discussions felt a little rushed, so longer would probably be better. I encouraged people to take extra time to reflect afterwards.
